4. The Four Layers
The Earth is composed of four different layers. The crust is the layer that you live on, and it is the most widely studied and understood. The mantle is much hotter and has the ability to flow. The outer core and inner core are even hotter with pressures so great you would be squeezed into a ball smaller than a marble if you were able to go to the center of the Earth!

5. CRUST:
Composition:
Made of Silicon (Si), Oxygen (O), and Aluminum (Al)
Thickness:
The thinnest layer
0-32 KM ( miles)
State of Matter:
Solid cool rock
Temperature:
200° to 400°C (392°F to 752°F)

6. Still CRUST: Interesting Facts: The outermost layer of the earth
Two types of crust: oceanic, continental
Oceanic (ocean floor) is thinner
continental (mountains) is thicker
It is part of the Lithosphere.
Lithosphere: crust and upper mantle

7. MANTLE Composition: Made of Magnesium (Mg), Si and O. Thickness:
The largest layer
2,868 KM (1,800 miles)
State of Matter:
Plastic-like - Hot liquid magma
Temperature:
870° to 2200°C (1,598°F to 3992 °F)

8. Still MANTLE: Interesting Facts:
There are three parts: Upper mantle, Middle Mantle, and Lower Mantle (80% of Earth)
No one has ever drilled into the mantle.
It is part of the Asthenosphere.
Convection currents cause UPLIFT, moving molten rock closer to the crust/surface.
Tectonic plates move around on the mantle.

9. THE Outer CORE Composition: Made of Iron and Nickle Thickness:
2,300 KM (1,429 miles)
State of Matter:
Hot molten liquid
Temperature:
2200° to 5000°C (3992° to 9032 °F)

10. THE Outer CORE Interesting Facts:
The outer core spins around the inner core.
This motion creates a magnetic center.

11. THE Inner CORE Composition: Made of Iron and Nickle Thickness:
1,300 KM (808 miles)
State of Matter:
Solid iron
Temperature:
5000° to 6000°C (9032° to °F)

12. THE Inner CORE Interesting Facts: Is the hottest layer of the Earth.
Is a magnet due to the spin of the outer core.
